Additive manufacturing (AM) is the most remarkable manufacturing technology developed in recent years. With this technology, it can produce products directly from a computeraided design model. In this respect, AM technologies can provide parts in less time compared with traditional production methods by producing less waste with a shorter processing step and will be very important for future industry applications because of these features. [1-5] Selective laser sintering (SLS) is a process of bonding (sintering) powder particles to each other by exceeding the melting temperature utilizing a laser beam. SLS machines can be given different names. EOS GmbH (Germany) has described this process as direct metal laser sintering (DMLS). [6,7] DMLS is an advanced technology that enables the rapid production of complex-shaped 3D parts using metal powders. [8] DMLS has a unique ultrafine and metastable microstructure, thanks to its fast solidification rate (10 3-10 8 K s À1). [9] This rapid solidification results in high thermal gradients and short interaction time. Thus, the microstructures of DMLS-produced materials are different than those produced by conventional methods. Tool steels produced by AM methods also have microstructures that are quite different from traditional cast-tool steels. Due to the advantages of the SLS method, it is widely used in aerospace, medical, defense, and automotive industries. AlSi10Mg, titanium, stainless steels, composites, tool steels, and Ni-based alloys can be produced by the DMLS method. [10-15] The name "Maraging" comes from the combination of martensite and aging. [16] Maraging steels (MS1) are valuable materials due to their excellent formability, weldability, toughness, and high strength. Therefore, it is preferred in critical applications such as submarine bodies, gears, rocket engine cases, aircraft components, pressure vessels. [17-22] 18Ni-300 MS1 is used in the AM processes. MS1 is a steel that can be aged, and forms precipitates such as Ni 3 Mo, Ni 3 Al, Ni 3 Ti, Fe 2 Mo, etc. [23-30]. MS1 is a fascinating steel for engineering applications because of its good weldability, machinability, and surface treatment. MS1 produced with DMLS show low strength in as-built condition. Various heat treatments are applied to this material to increase strength. These heat treatments are directly aged from the as-built state (aged) and solution and after aging (SHT) heat treatments. [31,32] In the literature, MS1 studies that were produced by the SLM method have been done before, but these are limited. Also, no research has been done about MS1 produced by the DMLS

“…In addition to undeformed chip thickness, a larger number of arbitrarily oriented abrasive particles will establish contact with the workpiece as the depth of cut increases. The associated increase in grit depth of cut enhances shearing and ploughing action on the surface which further contributes to increased grinding force [ 33 , 34 ]. The temperature developed in the grinding area plays an essential role in governing the grinding force since the sharpness of the grit depends on the temperature and adhesion of the material [ 26 ].…”

Additive manufacturing (AM) is replacing conventional manufacturing techniques due to its ability to manufacture complex structures with near-net shape and reduced material wastage. However, the poor surface integrity of the AM parts deteriorates the service life of the components. The AM parts should be subjected to post-processing treatment for improving surface integrity and fatigue life. In this research, maraging steel is printed using direct metal laser sintering (DMLS) process and the influence of grinding on the fatigue life of this additively manufactured material was investigated. For this purpose, the grinding experiments were performed under two different grinding environments such as dry and cryogenic conditions using a cubic boron nitride (CBN) grinding wheel. The results revealed that surface roughness could be reduced by about 87% under cryogenic condition over dry grinding. The fatigue tests carried out on the additive manufactured materials exposed a substantial increase of about 170% in their fatigue life when subjected to cryogenic grinding.

“…The aging parameters (time and temperature) affect the mechanical properties and dimensional changes in maraging steel. This is attributed to the diffusion of alloying elements from the nickel-martensite matrix during aging [5]. The formation of defects in such Abstract The hardened 18 % nickel maraging steels find potential application as an engine component for heavy vehicles and as armour metal in defence.…”
